ABC of Content Validation and Content Validity Index Calculation

Education in Medicine Journal, 2019
There are five sources of validity evidence that are content, response process, internal structure, relation to other variables, and consequences. Content validity is the extent of a measurement tool represents the measured construct and it is considered

K-MACE and Kernel K-MACE Clustering

IEEE Access, 2020
Determining the correct number of clusters (CNC) is an important task in data clustering and has a critical effect on nalizing the partitioning results. K-means is one of the popular methods of clustering that requires CNC.

Determining at What Age Children Provide Sound Self-Reports: An Illustration of the Validity-Index Approach

Assessment (Odessa, Fla.), 2020
In psychological assessment of children, it is pivotal to establish from what age on self-reports can complement or replace informant reports. We introduce a psychometric approach to estimate the minimum age for a child to produce self-report data that ...

A New Fuzzy Cluster Validity Index for Hyperellipsoid or Hyperspherical Shape Close Clusters With Distant Centroids

IEEE transactions on fuzzy systems, 2020
Determining the correct number of clusters is essential for efficient clustering and cluster validity indices are widely used for the same. Generally, the effectiveness of a cluster validity index relies on two factors: first, separation, defined by the ...
